3(Ꮾ - f) -4 = 3f - 4

raketka [301]

3(6-f)-4=3f-4

First is expand

18-3f-4=3f-4

Combine like terms

14-3f=3f-4

18-3f=3f

18=6f

f=3

Viefleur [7K]

Given that the number of possible handshakes within a group of n people is given by the equation:

 $N= \frac{1}{2} (n^2-n)$

Given that there are 105 people at a party, the number of possible handshakes is given by:

 $N= \frac{1}{2} (105^2-105) \\ \\ = \frac{1}{2} (11025-105)=10920$

the quadratic function h (t)=-16t^2+150 models a balls height, in feet, over time, in seconds, after it is dropped from a 15 sto

natulia [17]

Hello! Lets solve this :)
So for the first question :
h(t) = -16t^2 + 150
h(0)= -16 (0)^2 + 150
h(0)= -16(0) + 150
h(0)= 0 + 150
h(0)= 150 feet

Second question
We need to find here the time when the ball hit the ground; or when the height h(t) is 0.
In equation form
h(t) --> 0=16t^2 + 150
16t^2 = 150
t^2=150/16
t= √150/16
t= 5√6/4
t= 5 (2.45)/4
t= 3.06 seconds

Hope this helps! If you have any other questions or would like further explanation just let me know! :)
